At 1:48am, Millwood FD Ladder 52 was requested to the Briarcliff Manor Fire Department for a laundry room fire. Upon the arrival of Car 2051 (Briarcliff Manor Chief), a 10-75 (Working Fire) was transmitted for a fully involved structure fire, bringing a FASTeam from Croton-on-Hudson Fire Department, an engine and ladder from Ossining Fire Department and an ambulance from Ossining Volunteer Ambulance Corps. Soon after the working fire transmission, Car 2051 requested a second alarm assignment, bringing an engine from Pleasantville Volunteer Fire Department, a ladder from The Chappaqua Fire Department, a cascade unit to fill air bottles from Buchanan Eng Co. and a rehab unit from Pleasantville Volunteer Ambulance Corps. Millwood members arrived on scene for manpower and utilized a 2.5 inch hoseline to AB corner of the building, but were removed from that corner due to collapse. Members then moved to the BC corner and use their hoseline to cool down a nearby propane tank, as well as continuing to hit the structure with water as it fully collapsed. During this incident, Thornwood Tower Ladder 1 and Pocantico Hills Engine 189 relocated to Briarcliff Manor headquarters in case of any other calls in district. Millwood units were back in service about 3 hours later.
